FindByCounty() 这个函数应该转到数据库并提取信息。将信息存储在各自的类中(它确实如此)......但那又是什么?
public EditCountyViewModel FindByCounty(string countyName)
{
var parameters = new DynamicParameters();
parameters.Add("@CountyName", value: countyName);
var query = @"SELECT counties.id
, counties.CountyName
, counties.Website
, counties.Address
, counties.City
, counties.State
, counties.PhonePrimary
, counties.PhoneAlt
, counties.RecordsOnline
, counties.BackToYear
, counties.Cost
, products.ProductName
, products.Description
, countyproduct.TurnTime_MinHours
, countyproduct.TurnTime_MaxHours
, countyproduct.Price
FROM
counties, countyproduct, products
WHERE
counties.CountyName = @CountyName AND countyproduct.countiesID = counties.ID AND countyproduct.productsID = products.ID;";
EditCountyViewModel editCountyVM = new EditCountyViewModel();
EditProductsViewModel editProductVM = new EditProductsViewModel();
editProductVM.ProductList = this.db.Query<Product>(query, new { countyName }).ToList();
editCountyVM.county = this.db.Query<County>(query, new { countyName }).FirstOrDefault();
return editCountyVM;
}
HOMEcontroller上的详细信息() 我想我应该只查询所有信息,然后在此函数中使用LINQ来分割出我需要的信息。
public ActionResult Details(string countyName)
{
var model = repository.FindByCounty(countyName);
return View(model);
}
正如我的代码所代表的那样,它不会运行,因为在FindByCounty()
中它只返回一个所需的元素editCountyVM
。现在我可以更改函数的输出并返回另一个editProductVM
但是我没有第一组信息(editCountyVM)。
我认为问题是我要获取此信息的方法。任何帮助将不胜感激。
答案 0 :(得分:1)
听起来如果您想同时返回editCountyVM
和editProductVM
,您可以将方法的返回类型更改为Tuple<EditCountyViewModel,EditProductsViewModel>
。然后按如下方式生成return语句:
return new Tuple<EditCountyViewModel,EditProductsViewModel>(editCountyVM, editProductVM);
